[The psychiatric patient with deficits: a study of patients presenting at the emergency medical service].

We present the six months prospective study results assessing clinical, social and demographic features in defectual psychiatric patients (chronic psychosis, dementia syndrome, intellectual deficit) who went to Basurto Hospital's Emergency room during that period of time. The studio data were obtained applying a clinical epidemiological questionnaire. Some problems derived from attending these patients were analyzed. Suggestions to improve the efficacy of the defectual psychiatric patient's assessment are proposed.
